Description

[Detailed explanation of the idea] The present invention relates to a knife sheath.

Traditionally, the sheath of a wooden knife would naturally expand and contract, causing the knife to become stuck inside the sheath.
Or, conversely, it may fall off naturally.
The defect was that the handling was dangerous and inconvenient.

Also, as shown in FIG. 1, after forming a recessed knife body accommodating part 1b on one side of the plate material 1a, another plate material 1c of the same size is matched with the knife body part 1b, and both are glued together to form a sheath shape. In the method of forming a sheath by machining the housing part 1b, it is difficult to form a recess in the housing part 1b, especially to form a sharp tip part, and it is difficult to form a sheath by machining the housing part 1b.
1c may be glued out of alignment with each other, etc.
There was a defect in that it took time to manufacture.

The purpose of the present invention is to eliminate such defects and to easily manufacture a scabbard body that looks good by forming the scabbard body from a single piece of wood and carving storage grooves of the same width into it. The goal is to provide knife sheaths that can be used.

Another object of the present invention is to prevent the storage part of the sheath body from shrinking by the holding member that is fitted and fixed in the storage groove, and to keep the knife at a suitable level of firmness at all times with the gripping part provided on the holding member. The aim is to provide a knife sheath that can be used to store and hold the knife.

The first embodiment embodying the present invention will be described below in the second to second embodiments.
To explain Figure 4, 1 is a knife sheath body formed of a single piece of wood, and 2 is a storage groove carved with the same width on the back surface of the knife, which extends over the entire length of the sheath body 1. ing. Note that 3a is the handle of the knife. Reference numeral 4 denotes a holding member that is fitted and fixed in the storage groove 2 of the sheath body 1, and its material is synthetic resin, which does not easily expand or contract naturally due to temperature changes, especially when exposed to heat. Strong polyacetal, polycarbonate, etc. are most suitable.
Reference numeral 11 denotes a cap portion of the holding member 4, which is attached to the sheath body 1.
It is designed to come into contact with the proximal end surface of.

Reference numeral 6 denotes a square tubular fitting protrusion formed on the front surface of the mouthpiece 11, and is adapted to be fitted into the base end of the storage groove 2 of the sheath body 1. Reference numeral 5 denotes a locking hole that extends through the fitting protrusion 6 in the front-rear direction, and is cut out at the bottom. The fitting protrusion 6 constitutes the clamping part in this embodiment, and since the lower part 5a of the locking hole 5 converges in a V-shape, the body of the knife It is designed to be held with just the right amount of firmness.

Reference numeral 7 denotes an insertion portion extending from the upper part of the fitting protrusion 6 toward the distal end side, and is adapted to be inserted into the back of the storage groove 2 of the sheath body.

In addition, it is preferable to use an adhesive to fix the holding member 4 and the sheath body 1, and when using an adhesive, the outer periphery of the fitting protrusion 6 and the insertion part 7 should be formed in a rough shape. This allows for more effective adhesion.

In this sheath, the fitting protrusion 6 and insertion part 7 of the holding member 4 are inserted into the storage groove 2 of the sheath body 1.
Shrinkage of the storage groove 2 in the width direction is reliably prevented.

Furthermore, since the sheath main body 1 is made of a single piece of wood, it has a good appearance, and unlike the conventional case, there is no risk of the two sides of the storage groove 2 shifting relative to each other, making it easy to manufacture. Furthermore, since the storage grooves 2 have the same width, the engraving work is extremely simple.

When the knife body 3 is placed in the sheath, the knife body 3 is held by the locking hole 5 of the fitting protrusion 6 in the holding member 4. Even if the storage groove 2 of the sheath body 1 attempts to contract, this contraction is reliably prevented by the fitting protrusion 6 and the insertion part 7 of the holding member 4. Conversely, even if the storage groove 2 becomes larger, the holding member 4 does not expand and continues to act reliably on the shell 3 as described above, so the shell 3 will not accidentally fall out of the sheath. do not have.

Therefore, the knife body 3 is always housed and held within the sheath with a constant and moderate pressing force regardless of the expansion and contraction of the sheath body 1.

The holding member 4 is made of a heat-resistant synthetic resin such as polyacetal or polycarbonate, so it can withstand heat generation during rubbing, and the sheath body 1
It can be easily combined with the main body 1 in the assembled state. Furthermore, due to the elasticity of the synthetic resin, a suitable holding effect on the knife body 3 described above can be obtained.

Next, a second embodiment of the present invention will be described with reference to FIGS. 5 and 6.

In this embodiment, the insertion portion 7 of the holding member 4 is
A hemispherical head 9 made of synthetic resin that comes into contact with the distal end surface of the sheath body 1 is provided at the tip to form a double-ended sheath.

Furthermore, a third embodiment of the present invention will be described with reference to FIG.

In this embodiment, a finger rest 10 is provided on one side or both sides of the mouthpiece 11 of the holding member 4, and by hanging the thumb on the finger rest 10, the body 3 of the knife housed in the sheath can be held. This makes it possible to perform the extraction operation reliably and safely.

Note that the finger hook portion 10 is connected to the cap portion 11 of the holding member 4.
It may be provided protrudingly on the dorsal side or recessedly provided on the side part.

In each of the above embodiments, the body 3 is held in the lower part 5a of the locking hole 5 in the fitting protrusion 6, but as shown in FIG. A structure may be adopted in which a protrusion 12 is provided and the body 3 is held by engaging the protrusion 12 with the body 3.

As detailed above, the present invention makes it possible to easily manufacture a scabbard body with good appearance by forming the scabbard body from a single piece of wood and carving storage grooves of the same width into it. The holding member that is fitted and fixed in the storage groove prevents the storage portion of the sheath body from shrinking, and the holding member provided on the holding member allows the knife body to be stored and held with just the right amount of firmness at all times. This is a practically preferable idea for a knife sheath because it has the following effects.
